The NSW Upper Hunter by-election on 22 May was notable for the unusually low first preference vote for the two major parties. The Nationals polled 31.2%, Labor 21.2%, with the combined vote for the other 11 candidates an unusually high 47.6%.
The by-election was conducted under NSW’s optional preferential voting rules and 63.4% of other candidate ballot papers exhausted their preferences before reaching one of the final two candidates. At the end of the count, exhausted ballot papers represented 30.2% of the first preference vote.
